Rockets guard Jeremy Lin went through practice on Thursday for the first time since hurting his back four days ago.

He was recovering from a knee injury when he started having back spasms.

While he went through the light practice, Lin said he is unsure if he will be ready to play when the Rockets play at Indiana on Friday.

“I am definitely not where I want to be in terms of where I was before,” he said. “Today was the first time I did anything basketball-wise. We will see how it feels tomorrow and then build from there.”

Lin said that he had some trouble just getting around in practice.

“Being able to move, driving by people, jumping, shooting,” he said.”It’s expected. I didn’t move or sweat for four days so it is going to take a little bit of time
